pnmscalefixed
Scale images using fixed-point arithmetic
TLDR
Scale image using fixed-point math
$ pnmscalefixed [2.0] [input.pnm] > [output.pnm]
Scale to specific dimensions$ pnmscalefixed -width [800] -height [600] [input.pnm] > [output.pnm]
SYNOPSIS
pnmscalefixed [options] scale [file]
DESCRIPTION
pnmscalefixed scales PNM images using fixed-point integer arithmetic instead of floating-point math. This makes it faster than pamscale on systems without hardware floating-point support, at the cost of slightly reduced accuracy.The tool accepts a scale factor or target dimensions via -width and -height. For most modern systems, pamscale is preferred for better quality. Part of the Netpbm toolkit.
PARAMETERS

Scale factor.-width n
